Portal milling machine PR
With fixed portal and movable machine table
Portal milling and boring centers of the PR series offer maximum precision and flexibility for machining the large parts of complex and high-precision workpieces. Outstandingly suitable for high-precision machining of prismatic and cubic workpieces in the mechanical engineering and tool and mold making sectors. An extremely heavy cast iron design with optimum damping properties and the INA linear guiding system equipped with hydro mechanical damping slides as the basis for the ultra-modern PR portal milling and boring centers.
Optionally available in gantry design.
